MANIFOLD-HEATER.

' Specification of Letters Patent.

Patented Nov. 9, 1929.

Application filed January 2, 1920. Serial No. 349,057.

To aZZw/Lmnc't may concern:

Be it known that I, Enwann BOWMAN, a citizen of the United States,residing at Dubuque, in the county of Dubuque and State of lowa, haveinvented a certain new and useful Improvement in lilanifold-Heaters. ofwhich the follow ng is a specification.

This invention relates to an intake manifold heater for automobiles.While the drawings show such a device for a popular make of car now madein very large quantities, the irwention is not limited to that specificform of device shown.

The object of the invention is to provide a rum-electric manifold heaterwhich can be readily applied to the manifold of an automobile andparticularly to the specific car above referred to, which can be easilyput in place and removed therefrom, which does its work well and is notliable to get out of order. The invention consists in mechanism capableof carrying out the foregoing objects, and also inmany features anddetails of construction which will be hereinafter more fully set forthin the specilication and claims.

deferring to the drawings in which like nume 'als represent the sameparts through out the several views.

Figure l is a side view of the manifold side of the engine of anautomobile, showing the mechanism of this invention in its preferredform applied. thereto.

Fig. 2 is a sectional detail view on the "line 2-2 of Fig. 1.

Fig. 8 is a perspective view, the parts constituting the mechanism ofthis inven tion separated one from'the other.

Broadly speaking, the invention consists in a portable oil heated lampor furnace applied to the manifold of the engine in such a way that theheat generated by the lamp of the furnace has ready access to the pipesof the manifold. In Figs. 1 and 2, the de vice is shown applied to themanifold piping system 10 of the engine mechanism 12. It consists of anirregular shaped box or case it preferably but not necessarily having aninclined roof 16 leading to a large opening 18 giving access to themanifold pipes 10 of the engine. The face 30 of the box, which surroundsthis opening 18, is in the particular case here illustrated providedwith. integral ribs 20 which enter the vertical spaces usually foundbetween the manifold pipes 10 so as to make a practically gas tight fitabout the opening 18. Projecting from the upper portion of the box is aflange 22 having ears 24: through which are perforations 26 for securingdevices such as pins 28 on standard clamps 29 of the automobile of theclass described arranged to secure the device to the manifold side ofthe engine in any convenient manner. In the particular car for which thedevice is designed, these clamps are part of the engine equipment andare merely released long enough to apply the heater. Also projectingfrom the face 30 of the box in which is opening 18 and above thatopening is a horizontal lug or flange 32 adapted as clearly shown inFig. 2 to fit between adjacent pipes of the manifold and thus insure hotgases created in the box to pass through the opening 18 and pass thepipes 10.

The heating equipment of the box consists of some sort of wicking 34,adapted for impregnation with alcohol or the like, located in areceptacle 36 mounted on a drawer 38 slidable in and out of the box fromthe left as viewed in Fig. 2. The drawer carries a closure plate or doord0 interfitting with the box as shown in Fig. 2. The drawer ismanipulated by a handle 42 and is locked in place by some suitable formof spring catch, as for instance the spring 4d engaging the lower edgeof plate 30 at L6 as shown and adjustable with reference to the drawerby the screw 48. Access of air to the device is provided by perforationsin the bottom plate 38 and by a notch or other suitable opening 52 inclosure member 40.

The stove mechanism 3d36 is provided with a suitable removable cap 54:adapted to be placed over the contents of the cup 36 to extinguish theflame from wick 84 in the usual manner with alcohol lamps and to retainthe fuel material therein without evaporation when the device is not inuse.

In the operation of the device, the parts shown in Fig. 4 are soldcommercially in assembled form. The purchaser, on obtaining one of theseequipments, takes hold of handle 42 and pulls it to the left as shown inFig. 2, thus automatically releasing spring 44 and bringing the parts tothe position of Fig. 3. After removing the cap 54 and filling the cup 36with alcohol or other suitable material, the operator lights it. eitherbefore replacing the drawer or after, practically or wholly replacing itby inserting a match through perforation i0.

The device is allowed to burn in the position shown in Fig. 2 until themanifold mechanism 10 is sufiiciently warm, whereupon the operatorremoves the drgwver, extinguishes the flame by putting the cap--54 overchamber .36, thenreplaces the drawer and leaves the parts in assembledposition until such time asit is necessary'to again heat the manifold.In actual construction, the mechanism is made of such size and pr0-portion that the chamber 36 will contain suflicient liquid forasubstantial number of manifold heatings before it is again necessary torefill the chamber 36.

Having thus des ;ribed my invention what I] claim as new and desire tosecure by Letters Patent, is

'1; In mechanism of the class described, a box having a substantiallystraight side adapted to be applied broadside to a manifold, said sidehaving an opening adapted to be applied in proximity to the manifold ofan engine, means for attaching the box to the manifold, irregularinterfitting ridges on the unperforated portion of that face of the boxadjacent to the manifold conforming to the irregularities of the enginemanifold, and means for temporarily generating heat inside the box, anddelivering it through said opening.

2. In mechanism of the "class described, a box having an opening adaptedto lead to an'engine manifold, a drawer for said box removable therefromand alamp carried by said drawer adapted, when lighted, to deliver heatthrough said opening, to the manifold, there being suitable draftopenings through the drawer adjacent to the lamp, and a latch mechanismfor holding the drawer in closed position.

,3, In mechanism of the class described, a box having a drawer in itsbottom, a lamp carried by the drawer and removable with itfrom the box,means for detachably securing the drawer in place, an inclined roof forsaid box leading from the side, of the box through which the drawer isremoved upward to the other side of the box, there being a port in thelast mentioned side of the box through which heat given off by the lampmay pass to an engine manifold, and means on said last mentioned side ofthe box for securing it to a manifold, for the purpose set forth.

4. In mechanism of the class described, a box having a drawer in itsbottom, a lamp carried by the drawer and removable with it from the box,means for detachably securing the drawer in place, an inclined roof forsaid box leading from the side of the box through which the drawer isremovedupward to the other side of the box, there being a port in thelast mentioned side of the box through which heat given off by the lampmay pass to an engine manifold, means on said last mentioned side of thebox for securing it to a manifold, and a. deflecting plate 32 at the topof the opening leading to the manifold adapted to enter the manifold andforcegases from the device to pass entirely through the manifold, forthe purposes set forth.

In witness whereof, I have hereunto sub-- scribed my name in thepresence of two witnesses.

EDWARD BOWMAN.
